I tried everything. I cleared Illustaror with CC Cleaner, I installed Extension Manager to see if it is conflicting the instalation. It won't update =(

Also when I run Illustrator and there is a "New Features" pop up window, I click in "see all the new features", it popup a blank notepad and another system new message: "the filename, directory name, or volume label syntax is incorrect". When I try to use Typekit fonts it happens the same thing...
